New Grey's Anatomy Sneak Previews: Mer in Peril

Things are not looking good for several doctors tonight on Grey's Anatomy.

In the first set of sneak peeks from the winter premiere, airing this evening at 9 p.m. EST, we saw Cristina Yang in a state of emotional turmoil. Her best friend Meredith Grey, meanwhile, may be the one truly in harm's way.

In this longer version of an earlier sneak preview clip, we see the wreck that leaves Mer and Alex struggling to save lives, while potentially risking their own. You can feel the suspense build in the 90-second clip below:

What do you think will happen to Meredith? And to Cristina? As if things weren't awkward enough for the latter, another sneak peek (below) shows Teddy in a downright giddy mood in the operating room. Yikes.

Watch that and the Canadian promo for "Suddenly," if you missed it, here:
